Col4a2 mutation disrupts cerebral artery function in aged mice

In 12-month-old Col4a2 mutant mice, cerebral pial arteries showed impaired myogenic tone driven by PKA-dependent remodeling of ryanodine receptor clusters.In 12-month-old Col4a2 mutant mice, cerebral pial arteries showed impaired myogenic tone driven by PKA-dependent remodeling of ryanodine receptor clusters.

Age-dependent impairment of pressure-induced myogenic tone in cerebral pial arteries, but not parenchymal arterioles, from Col4a2+/G646D mice.

Distracted driving slows emergency braking in older adults

In a driving simulator, dual-demand trials slowed older drivers' braking to 776 ms versus 605 ms in younger adults, with error rates reaching 11.67% compared to 3.04%.In a driving simulator, dual-demand trials slowed older drivers' braking to 776 ms versus 605 ms in younger adults, with error rates reaching 11.67% compared to 3.04%.

Exercise missed primary cognitive goals in cancer survivors

In 253 breast cancer survivors, a 12-month exercise program failed to beat wellness calls on primary cognitive tests, despite selective gains in attention and memory.In 253 breast cancer survivors, a 12-month exercise program failed to beat wellness calls on primary cognitive tests, despite selective gains in attention and memory.
